Rubella Virus Antigen >90%

Viral antigen preparations form the capture component of rubella serology assays, and this liquid-format product from Antibodies.com delivers >90% purity for enzyme immunoassay (EIA) workflows. Rubella virus is a single-stranded RNA pathogen (family Togaviridae, genus Rubivirus) responsible for German measles; measuring patient IgG and IgM reactivity against purified viral antigen determines immune status and guides prenatal screening for congenital rubella syndrome risk. The 1mg size supports solid-phase coating of diagnostic microplates, vaccine immunogenicity studies, and reference serum calibration. Researchers conducting seroprevalence surveys, vaccine potency work, and cross-reactivity testing benefit from the >90% purity threshold, which reduces nonspecific binding and improves assay signal-to-noise. Each lot is quality-controlled by SDS-PAGE and validated against reference rubella antisera to confirm reactivity. Storage at -80°C in single-use aliquots preserves antigenic integrity across repeated freeze-thaw cycles, while the liquid preparation eliminates reconstitution steps common with lyophilized antigens. Intended for research use only in assay development, antibody characterization, and immunogenicity profiling.
